Specification of Letters Patent? K Patented Aug. '7, 1917.

7 Application filed December 8, 1915. Serial No; 6 5,857.

Be it known that I, ROY J. BUELL, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Attachments for Bath- Tubs, and declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make'and use the same, reference being had to the accom panying drawings, which form a part of this specification.

This invention relates to attachments for bath-tubs and its object is a device combining in a single unitattachable to the tub, a water-tank, a'heater therefor, a fuel supply tank and a pump for withdrawing the water from the tub. The tank is provided with anoutlet leading into the tub and a fixture is provided connecting the outlet of the tub and the pump attached to the-water tank. Another object of the invention is a heater so arranged that the water as it becomes heated is delivered adjacent to the 7 outlet of the tank so that on opening the said outlet to allow the water to flow into the tub the firstwater drawn is the warmest water and continues to flow principally from the tank through the heater until the tank is empty. A further object is a combined tank approved form,

and heating appliance that may be readily attached or detached from the tub and when attached is movable with the tub being entirely supported thereby. These and other objects and the several, novel features of construction are hereinafter-more fully described and claimed and shown in the accompanying drawingsin which- Figurel is a verticali section ofa water heating unit, embodyingmy' invention supported on a bath tubl 5 f Fig. 2 is a section ftakenon line rww of Fig.1. '5 i Fig. 3 is a plan view of the 'water'tank and attached instrumentalities.

- Similar characters refer to similar parts throughout the drawing and specification. "Thetubl preferably of metal and of any rim '2 and waste outlet The tub is prefra ly per le shown, b g i pported is provided with'theusual Arum *oF '1 in a framework 4 mounted onrollers 5, and. the partlcular utility of the combined tub and water-heating device is its adaptability for use .in towns and villages and other places in which no common water supply system is provided. With my device a simple, inexpensive and efficient apparatus is provided for heating water for bathing purposes and'for readily removing used water from the tub. i

In the embodiment of the invention here shown a'tank 6 for water is provided having a cover 7 at the top and, as shown in Figs. 2 and 3, the tank is provided with brackets 8, 8 attached thereto and adapted to rest on the rim 2 of the tub. Asis also shown in Fig. 2, the water tank is narrower at the top than at the bottom. the large portion thereof fitting beneath the rim 2 of the tub and the bracket so spaced from such enlarged portion that the shoulder of the tank is held tightly against the rim with the vertical wall 9 thereof closely engaging the wall 10 of the tub. The-walls 9 and 10 arelsimiv bulb 17- on the lower en'd thereof by means of which air may be forced into thetank to produce af'pressure on the fuel to insure a proper feeding thereofto the burners located beneath thcwate'r tank and connectingwithftheffuelitank by means of'apipe line 18. The "preferable'fifuel, is gasolene, andtheburners are shownfsomewhat diagrammatically but are of the ordinary well end of-thetank 13 is a tube 15 having a known type" for burning kerosene .or gaso l'e'nej The burners are shielded a depending apron or flange 19 as shown more particularly in Fig. ,2.

The bottom of the water tank'6 'isprovided with recesses or pockets 20 and 21,0ne'above each-{burner 17 into heat from each In these pockets in each instance: is a which the ifiame and burner respectively rises.

pipe 22 arranged in a cone shaped coil so that each turn of the pipe is exposed to the flame and heat from the burner.

the end of the pipe passes through the pockets as is indicated in Fig. 1. The upper The portion 38 horizontal wall of the pocket 25 is apertured at 26 preferably in several places and the vertical Wall is provided with an aperture or apertures 26 at the bottom of the tank through which it may bedrained.

, The purpose of the pocket 25 primarily is to provide a means of segregating the heated water from the colder water of the tank so that on opening the fitting 11 to allow the water to flow from the tank the first water drawn is the hottest water and the purpose of the apertures 26 is to enable the entire. contents of the tank to become heated when the valve 11 is closed. The heated water from the coil flows into the pocket 25 upward through the apertures 26 and the colder water enters the coil through the inlet 23. As the pocket 25 incloses the outlet it is necessary to provide the drainage apertures 26 7 Connected with the waste outlet 3 of the tub is a one piece fitting 27 shown clearly in Figs. 1, 2 and 4:. The fitting has an end 28 threaded to receive the threaded portion of the apertured outlet plug of the tub and also has an elongated portion terminating in an upturned internally threaded end 29 to receive the threaded end of the pump cylinder 30 as shown in Fig. 1. The pump may be of any approved type adapted'for the purpose preferablyone having a piston 31 provided with a ball valve 32 and the lower end of the pump cylinder is provided with a ball check valve 33 opening on up ward movement of the pump piston and closing on the downward stroke during which the ball andvalve 32 of the piston opens allowing the water to flow through the piston to the upper side thereof in the usual well known manner. The upper end of the pump cylinder is provided with an outlet spout 34:, and an operating rod 35 is attached to the piston provided .at the upper end with a handle .by means of which it may be operated. The pump cylinder stands vertically at the side ofthe water tank and may be secured inposition by any approved means as a strap 36 passing about the pump cylinder and secured to the wall of the tank.

, The fitting 27 is provided with a downwardly; eXtending portion 38;having an internally threaded end to receive a'plug 39. of the fitting is also provided with an internally threaded aperture 40 adapted to receive a drain valve 41 as indivalve 41 as may be desired, and by providing the fitting with the plug 39 the said plug may be removed and a drain pipe at tached in place thereof whenever the tub is set in permanent position.

By my improved water heating device, the several elements of which are united to pro vide a. single unit attachable to the tub, a bath tub of ordinary form may be utilized without involving particular expense by simply mounting the device upon the end thereof as described. An inexpensive bathing appara tus is thus provided particularly adapted for use in isolated districts and enabling persons in such districts to avail themselves or" sanitary appliances equivalent to those in use in the larger towns and cities.
